One of my favorite computer systems, this one is in beautiful shape for its age. The IBM 5160 is an excellent system to use for testing hard drives for use in other systems. Remember though, some jumper changes will be necessary.">... [ read more ]

Compaq Portable 286by billdeg Total messages in this thread: 2 Updated: [ Compaq Portable 286 ] 10/22/2011  The Compaq Portable 286 is one of the rarest Compaq portables, very few were made with "Compaq Portable 286" nameplate.
This system has a 10MB hard drive and came with Compaq DOS, the original manual, and an AST add-on card of some type. The system will overheat after a few minutes. I need to spend more time with this one to get it running properly.

Greetings from MirandaSoft!by Kuya.Marc Total messages in this thread: 1 Hello Everybody! I am originally known, and still known as Marcos Miranda, the founder of MirandaSoft Computer Services in Seattle, Washington, USA, in July 1992. Though I have my own blog, it really looks like I should be part of VintageComputer.net. Though I can't contribute pictures, unless a USB port can be installed at the back of my head, I would like to post stories of my historical past, which is the original foundation and basis for my naturally-born Geek Life. Many, if not most of the pictures of computers posted in VintageComputer.net, are actual devices I had either operated and/or programmed, and I would like permission to use pictures from VintageComputer.net for my blog, showing the hardware that made me a geek, today. For those that don't know about me, or may have forgotten about me, here's some info to refresh those minds... I am 41 years old now. I learned abo">... [ read more ] |

An 8086 Monitor for an S-100 Bus systemby monahan_z Total messages in this thread: 1 I have been writing 8086 code for a fairly comprehensive 8086 monitor (~9000 lines of code) that with a number of new S-100 boards (an 8086 board, our IDE Board, our ZFDC board , our PIC-RTC Board and the Propeller driven Console IO board) allows one to boot MS-DOS. The goal is to have hardware and a BIOS so that standard generic MS-DOS (or FreeDOS) does not know it's not talking to a PC motherboard. This turned out to be more difficult than I thought. Most major PC software interrupts (0-20H) have to be emulated in very precise ways. Anyway delighted to say MS-DOS (V4.01) now boots up on 3.5" floppies or on a CF-Card with our IDE drive S-100 board. Thanks to this group BTW for suggesting NASM. Fantastic assembler If you have time take a look at http://s100computers...itor/8086%20Monitor.htm there are a few short videos there that show the">... [ read more ] |

Synertek VIM-1by billdeg Total messages in this thread: 1  The Synertek VIM-1 single board computer from 1978 was engineered around the 6502 processor and was very similar to the MOS/Commodore KIM-1. Later versions of the VIM-1 were renamed SYM-1 at some point early in production, making the VIM-1 rare, but also more likely to be "buggy". Note the message "SY1.0" that appears in the display.
I actually have two VIM-1 computers, they both boot to the SY1.0 monitor screen, so far, I will post updates as things progress.

Gateway 2000 P5-75by billdeg Total messages in this thread: 1  A very early home desktop personal computer (not a server) with a Pentium 75 processor, the Gateway 2000 P5-75.
I picked this system up from a computer repair store for $10. It's got Win 3.11 installed with a 16/4 ethernet card used to connect with an AS/400. I am not sure if Windows 95 would have been released yet, the chip dates are from 1994.
The P75 is pretty early Pentium. Even earlier was the Compaq Deskpro 5/66M which was featured in Byte July 1993. Cost, $9500.">... [ read more ]

Texas Instruments TM990/189 SBCby billdeg Total messages in this thread: 1  Here is a closeup of the Texas Instruments TM990/189 single board computer display sold by TI in the late 70's and early 80's. Click image for larger version.
This system is unique due to its calculator-type input panel and display. I was able to write and run a short program to add two hex numbers successfully. The computer is in like-new condition and operates very well.
 The TM990/189 looks like a TI 59 calculator stuck on a large computer board. Click image for larger version.

MITS Altair 220043K (43rd Kit made)by billdeg Total messages in this thread: 1 Bruce Damer's YouTube video about the oldest mint condition Altair 8800 computer.... http://www...h?v=nuMCs2Qym7Y From this video I learned that the first two digits of the original MITS Altair 8800 were always 22. Interesting. I discovered that right behind me in my workshop I have had the 43rd MITS Altair kit made. Serial number 220043K. Wow. This kit would have been shipped in January 1975. At the time there was a huge demand for the kits and I don't think it's unreasonable to assume they shipped at least 43 kits by the end of January. That also assumes the kits were mailed in the same order as the serial number, but I don't know. Bruce had factory-assembled #47, a boxed Altair 8800 with S/N 220047A - where the "A" indicates factory-assembled. Anyway just a factoid. Altair 8800 S/N 220043K A while ag">... [ read more ] |
